A multi-functional pen that has four ballpoint pen colors (black, red, blue, green) and a mechanical pencil function in one. Low writing resistance allows for smooth writingCompared to existing oil-based ballpoint pens, ``JETSTREAM'' achieves a smooth writing experience with low writing resistance regardless of writing speed. Equipped with ultra-low friction JETSTREAM ink. Clear and deep linesBy combining new coloring materials and pigments, we have achieved black density that is approximately twice that of conventional inks (black ink).* The photo in the explanation is an enlarged comparison of the drawn lines of the 0.7mm ball. Excellent quick-dryingThe newly developed ink soaks into the paper easily and dries very quickly.This reduces the stress of touching the drawn lines and getting your hands dirty, which is common with conventional oil-based inks. Equipped with a new spring tip and twin ball mechanism that prevents direct current and backflow of inkBuilt-in spring tip to support new smooth, low-viscosity ink. By pressing down on the ball of the pen tip, ink direct current (leakage from the pen tip) is prevented.In addition, the twin ball mechanism prevents ink from flowing backwards (ink flowing against the direction of the pen tip).
